Use the Due Date Calculator to determine the likely due date of your baby. Keep in mind that only 6% of babies are actually born on their due date. The Due Date Calculator shows the likely conception date, the end of the first and the second trimester dates - and of course the due date.

Enter the date of your last menstrual period and the number of days in your menstrual cycle into the Due Date calculator, and click on the Calculate button.

On average, there are 28 days in a menstrual cycle, but it can last from as little as 22 to as many as 44 days.
